Key Findings

  • 01The optimal formulation for consumer acceptance was 40% koro benguk flour and 60% purple sweet potato flour with 3ml of stevia sweetener.
  • 02The developed snack bar had significantly lower sugar (9.95%), salt (0.034%), and fat (19.71%) content compared to typical market snacks.
  • 03The product offered a good source of protein (14.94%) and dietary fiber (4.77%).
  • 04While nutritionally superior, the sensory preference score was lower than a commercial benchmark product.
02

Application

Design takeaway

Prioritize ingredient combinations and natural sweeteners that reduce sugar, salt, and fat while maintaining acceptable sensory attributes to capture the health-conscious consumer market.

How to apply

When developing new snack products targeting health-conscious consumers, experiment with alternative flours and natural sweeteners, and conduct thorough sensory evaluations to balance nutritional benefits with palatability.

Project actions

  • 01Consider using underutilized or novel ingredients to create unique product offerings.
  • 02Focus on reducing unhealthy components like sugar and fat while enhancing beneficial ones like fiber and protein.
  • 03Always compare your product's sensory qualities against established market benchmarks.

Method & Evidence

AimTo develop a healthy snack bar formulation using koro benguk and purple sweet potato flour with stevia sweetener, and to evaluate consumer acceptance and nutritional profile.
MethodExperimental design with sensory evaluation and chemical analysis.
ProcedureA 2-factor Completely Randomized Design was employed, varying the ratios of koro benguk and purple sweet potato flour (45:55%, 40:60%, 35:65%) and the amount of stevia sweetener (1.5ml, 3ml, 4.5ml). Consumer acceptance was assessed, and the nutritional content (moisture, ash, fat, protein, carbohydrate, fiber, sugar, salt) of the best-performing formula was analyzed.
ContextFood product development, healthy snack market.

Variables

IV["Ratio of koro benguk flour to purple sweet potato flour","Amount of stevia sweetener"]
DV["Consumer acceptance (sensory preference score)","Nutritional content (moisture, ash, fat, protein, carbohydrate, fiber, sugar, salt)"]
CV["Type of koro benguk flour","Type of purple sweet potato flour","Type of stevia sweetener","Baking/processing method"]

Strengths & Limitations

Strengths

  • +Addresses a clear market need for healthier snacks.
  • +Uses a systematic experimental design (2-Factor CRD).
  • +Provides detailed nutritional analysis of the developed product.

Limitations

The study focused on a specific set of ingredients and sweetener; other combinations might yield different results. The sensory evaluation might not capture all aspects of consumer preference.

Reliability & validity

The use of Two Way ANOVA and Kruskall Wallis methods for data analysis suggests a robust statistical approach. However, the validity of consumer acceptance scores depends on the representativeness of the sample and the clarity of the sensory evaluation criteria.

Think critically

While the developed snack bar is nutritionally superior, its lower sensory preference score compared to commercial products suggests a trade-off between health and palatability. How can designers balance these competing factors in future product development?

05

Design Principles

"Nutritional optimization through ingredient synergy and natural sweetening agents can lead to market-viable healthy food products."

This research addresses the growing market demand for healthier snack alternatives. By identifying an optimal ingredient ratio and sweetener level, it provides a tangible pathway for product developers to create appealing and nutritionally superior snack bars that align with consumer health consciousness.

06

What This Means for Your Design

Researchers created a healthier snack bar using less common ingredients and a natural sweetener, and people liked it, even though it wasn't quite as tasty as regular snack bars.
